A three-layer service-oriented architecture, driven by new data analysis and data modelling applications, providing data-intensive services and tools and integrating the community data infrastructure with Grid and HPC infrastructures

A great variety of data policies for data hinder seamless data access in Europe. Few examples are

Access to ESA/GENESI-DR: policy differs between data sets; access identification done via certificates (Posix …) but no own root CA: on going access gateways for different authentication methods. VERCE will interact with ESA/GENESI through EPOS and EGI-INSPIRE (VRC Earth Sciences). GENESI/ESA are going toward Shibboleth and SAML in synergy with EGI. VERCE will work on synergy both with EGI and GENESI/ESA.

Access to Earth System Grid (ESG) for climate data: openid and certificates (via myproxy at data centers). Data policies depend on the type of data and today only pragmatic solutions are available. VERCE will be in close contact with this community through EGI-INSPIRE (IPGP/IPSL), and the KNMI. At the KNMI projects of common portals is on progress.
